For applications where adjustable speeds are necessary, typically an AC motor with an Inverter or brush irrigation gearbox motors are used. Brushless DC motors are a sophisticated option because of their wide speed range, low temperature and maintenance-free operation. Stepper Motors provide high torque and smooth low speed operation.
Speed is typically controlled by manual procedure on the driver or by an external change, or with an exterior 0~10 VDC. Quickness control systems typically use gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid based on torque demands and budgets.
Mounting configurations differ to depending on space constraints or design of the application.
The drives are powerful and durable and show a concise and lightweight design.
The compact design is made possible through the mixture of a spur/worm gear drive with motors optimized for performance. This is achieved through the consistent application of light weight aluminum die casting technology, which ensures a high degree of rigidity for the gear and motor housing simultaneously.
Each drive is produced and tested particularly for every order and customer. A advanced modular system permits an excellent diversity of types and a maximum amount of customization to consumer requirements.
In both rotation directions, defined end positions are safeguarded by two position limit switches. This uncomplicated remedy does not just simplify the cabling, but also can help you configure the finish positions efficiently. The high shut-off accuracy of the limit switches ensures safe operation moving forwards and backwards.
A gearmotor delivers high torque at low horsepower or low swiftness. The speed specs for these motors are regular speed and stall-swiftness torque. These motors make use of gears, typically assembled as a gearbox, to lessen speed, which makes more torque offered. Gearmotors ‘re normally used in applications that need a lot of force to move heavy objects.
More often than not, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors can also be utilized as gearmotors … a lot of which are used in automotive applications.
Gearmotors have several advantages over other types of motor/equipment combinations. Perhaps most importantly, can simplify design and implementation through the elimination of the stage of separately designing and integrating the motors with the gears, therefore reducing engineering costs.
Another benefit of gearmotors is definitely that having the right combination of electric motor and gearing can prolong design life and invite for optimum power management and use.
Such problems are normal when a separate electric motor and gear reducer are linked together and result in more engineering time and cost and also the potential for misalignment leading to bearing failure and eventually reduced useful life.
Improvements in gearmotor technology include the use of new specialty components, coatings and bearings, and in addition improved gear tooth styles that are optimized for sound reduction, increase in power and improved life, all of which allows for improved functionality in smaller packages. More after the jump.
Conceptually, motors and gearboxes can be blended and matched as needed to best fit the application form, but in the end, the complete gearmotor is the driving factor. There are a number of motors and gearbox types that can be mixed; for example, the right angle wormgear, planetary and parallel shaft gearbox can be combined with long lasting magnet dc, ac induction, or brushless dc motors.
